A patient support apparatus includes a support frame. A projection housing may be rotatably coupled with the support frame. The projection housing may include a body defining an aperture. A light source is configured to emit a beam of light. A projector may be configured to direct the beam of light through the aperture in the body and onto a surface.

Novel tools and techniques are provided for implementing improved lighting components for a lighting element. A lighting element might include a cover. The cover might include a wall having an outer surface and an inner surface. The cover might further include one or more voids located between the outer surface and the inner surface of the wall. The cover and voids may be formed via one or more three-dimensional (“3D”) printing processes.

A lamp system applied to a vehicle according to the present disclosure is provided with any one of a reflector, an optical member, a digital micromirror display (DMD), a shield, or a shield optical module, and combined with a rotation light source device for generating light of a specific LED turned on at a synchronized rotation position of one or more LED chips of first to Nth LED chips (N is an integer of 2 or more) per one rotation while being rotated by a current application of a signal transmitter receiving a lamp turn-on signal of the vehicle, thereby generating various lighting patterns even while eliminating all problems of increasing the layout/decreasing the light amount/increasing the amount of property changed, lowering the reflection efficiency/transmission efficiency, and losing the optical efficiency with the circular LED array.

A system and method for reducing bird collisions with glazing utilizes a UV light source and a perforated opaque object. The UV light source is located adjacent an edge of a glass panel and is configured to project UV light rays onto a planar surface of the glass panel. The perforated opaque object is located between the UV light source and the planar surface of the glass panel, such that UV light rays passing through the perforated object cast onto the planar surface of the glass panel a UV shadow visible to birds and substantially invisible to humans.

An illumination device includes a plurality of light sources arranged in at least a first group of light sources having one or more light sources and a second group of light sources having one or more light sources and further includes one or more light collectors, each being arranged for collecting light from one or more light sources from the first group of light sources and for converting the collected light into one or more light beams. The first and second groups of light sources are each individually controllable. The first and second groups of light sources are both arranged for emitting light from a space on one side of the one or more light collectors. The illumination device is arranged so that light emitted from the second group of light sources through the one or more light collectors defines a pattern comprising one or more elongated elements.

A lighting element is disclosed that provides a projection of light forming a substantially uniform bright light on a surface a known distance from the lighting element. The lighting elements includes a dome lens that is removably positioned on a light source, such that the light source is retained at a location within a focal length of a projection lens and at or within a focal length of the dome lens. The dome lens magnifies the light outputted by the light source, such that the projected light is brighter than the light generated by the light source.
